Hi

As any body tried  this  project out?

www.arduino.org/learning/tutorials/boards-tutorials/franklin-lightning-sensor-as3935

I have af ranklin-lightning-sensor-as3935
Will a arduino uno work ?

website info they used a
Arduino Yun board

  Not sure if any of these can be used in WD    http://www.techlib.com/electronics/lightning.html  I have made three of these, two  can be seen there  https://flic.kr/p/s45YVT  &  https://flic.kr/p/sZYurD  , but I'm not sure how to connect them to WD or if it is possible to do so, they have a range of about 30/35 miles. If any knows how to connect them to WD (if they can) that would be good.

Those circuits are essentially the same function as the front end of the Hobby Boards lightning sensor. If someone has the original Hobby Boards schematic it would not be difficult to adapt it to use one of Charles Wenzel's detector designs as the front end.

  Hi Niko, Right I see, I will have to have a look on the internet to see if I can find any thing about it.

many thanks.

The front end (hopefully) generates a pulse for each strike, the rest of the Hobby Boards unit is a 1-wire counter that counts the pulses and provides the interface to the 1-wire bus so the count can be read by e.g. WD. I think a schematic may be in the Bitson Weather Toys book, but IIRC the final Hobby Board was not quite the same. ***

Be aware that these (Wenzel/Hobby Boards) are simple broadband receivers with very limited filtering so almost anything that generates an electrical discharge will set them off. Electric fences, welders, and heavy duty relays/contactors switching loads like motors can result in false readings. You might have something in your garage that sets it off  :wink:

The AS3935 chip which started this thread is a more sophisticated animal. I believe it's used in, or can be added to, the latest version of the blitzortung lightning device, and is used in some portable/pocket lightning alert devices. I was excited when it was introduced but have no personal experience with it. From what I have read it needs some tinkering with the settings to get a good result.
